Embodiment Construction

[0019] The new method for reducing the cutting edge radius based on the coating technology of the present invention can be used for processing various micro tools including turning, milling, drilling, grinding, planing and the like. The material of micro-tools can be typical tool materials such as single crystal diamond, polycrystalline diamond, cubic boron nitride, cemented carbide and high-speed steel. The method mainly includes the following steps: firstly, in a focused ion beam vacuum sample chamber, rough machining is performed on a micro-tool blank by using a high-energy and large-current focused ion beam to process a rake face of the tool. The focused ion beam can be typical application ion beams such as gallium ions, beryllium ions, and argon ion beams; secondly, the rake face is refined and polished by focused ion beam milling to reduce the roughness of the rake face and achieve smooth rake face preparation; Then the processed micro-cutter is put into the coating equi...
